load block: the assembly of shackle or hook, bearing, swivel, pins, frame and sheaves; the load chain or hoisting rope suspends this. This will include all accessories reeved in the hoisting ropes.
shall: a word used to show that a rule must be followed and is required.
normal operating conditions (of cab-operated cranes): during these conditions, the functions performed by the crane are within the original design’s scope. At the operating control devices is the operator, and no one else is on the crane in these circumstances.
pendant station: used for crane operating from the floor, these are controls suspended from the unit.
normal operating conditions (of floor-operated cranes): during these conditions ,the functions performed by the crane are within the original design’ scope. In these circumstances, the operator is off the crane operating control devices that are attached to the crane, and no one is on the crane.
service platform: workers perform repairs, inspections, maintenance,and adjustments of cranes under this provided means.
main hoist: used for lowering, coasting and lifting the rated load, this is the primary hoist mechanism .
noncoasting mechanical drive: when power is not available, this drive automatically results in decelerating a bridge or trolley.
parts of line: keeping up the load block, these are what the lines of rope number.
normal operating conditions (of remote-operated cranes): during these conditions the functions performed by the crane are within the original design’s scope. In these circumstances, at the operating control devices is the operator, and the operating controls aren’t connected to the crane.
overload: (see para. 2-188.8.131.52) any load that exceeds the rated load.
qualified person: by extensive experience, training, and knowledge or by possession of a certificate of professional standing, or a recognized degree in an applicable field, this person has demonstrated successfully the ability to resolve or solve issues relating to the work and subject matter.
lockout/tagout: a tag or lock’s placement on the device that isolates energy with a procedure that has been established.
primary upper-limit device: when actuated, this main device limits the upward direction of the hoisting motion.
reeving: a rope travels around drums or sheaves in this system.
rail sweep: located in front of the crane's leading wheels and attached to the crane, this device is used to remove obstructions.
main trolley: this trolley has an operator's cab connected to it.
rated load (capacity): manufacturer designated, this is the maximum load for which an individual hoist or crane is created.
runway: a crane travels on this assembly of beams, rails, brackets, framework, and girders.
sheave: used with a rope to change point of application of a pulling force and direction, this is a pulley or grooved wheel.
